Abstract
The N-(substituted 4-methylene-2-oxo-4H-benzo[e][1,3]oxazin-3-yl)isonicotinamide were synthesized by condensation of isonicotinic acid hydrazide derivatives with triphosgene. The structures of all the synthesized compounds have been elucidated by microanalysis and IR, NMR, MS spectroscopic measurements.
